Choosing an audio format
After making the required HDMI
®
ARC, eARC, or S/PDIF optical connection, go to
Settings > Audio > S/PDIF and ARC
option and select the audio format to use.
Choosing
Auto detect
is the easy solution, and generally provides good results.
However, if you have a high-end sound system and want to make sure you are getting
the best sound quality available in the programs you are watching, you can choose
another setting.
•
Auto detect
– Automatically detects the incoming audio format and
transcodes it to a compatible available format for the audio output (ARC,
eARC, or S/PDIF).
•
Auto passthrough
– Passes through the input audio to the connected receiver
without transcoding, sometimes resulting in better audio quality especially for
high-end audio formats such as those that take advantage of the higher
bandwidth of eARC, including Dolby MAT and Dolby Digital Plus 7.1, among
others.
•
PCM-Stereo
– Always outputs pulse-code modulated stereo, regardless of
input audio format.
•
Dolby Digital
– Converts all input formats to Dolby Digital.
•
Dolby Digital Plus
– Converts all input formats to Dolby Digital Plus.
•
Dolby Digital – DTS
– Converts all inputs except DTS to Dolby Digital. If DTS is
detected and the receiver supports DTS, passes through the DTS audio without
modification.
•
Dolby Digital Plus – DTS
– Converts all input formats except DTS to Dolby
Digital Plus. If DTS is detected and the receiver supports DTS, passes through
the DTS audio without modification.
Note
:
DTS audio formats are meant to be used with ARC, eARC, or S/PDIF
connections to a DTS-capable home theater receiver. If you use one of the DTS
options with the TV speakers, you might not hear any audio.
